Abstract: Dual connectivity operations described herein include splitting a PDU into at least first and second portions of data addressed to or from first and/or second network addresses of a wireless device respectively, and modifying a source/destination address of the second portion of data from the first network address to the second network address in the downlink direction, and from the second network address to the first network address in the uplink direction. Uniquely-marked bearers set up between relay access nodes and donor access nodes (and gateways associated therewith) enable transmission of portions of data to and from the different network addresses.

Abstract: Systems, methods, and processing nodes are related to preventing message overloading in a wireless network. The method includes establishing, by the access node, the wireless connection with the wireless device. The method also includes forwarding, from the access node to a controller node, a network connection message from the wireless device. The network connection message requests connection to network services of the wireless network. Additionally, the method includes receiving, at the access node from the controller node, a message indicating that the wireless device is denied access to the network services. Also, the method includes terminating, at the access node, the wireless connection with the wireless device in response to receiving the message. The method further includes limiting, at the access node, an establishment of future wireless connections with the wireless device in response to receiving the message.

Abstract: Contention-based random access operations are enhanced by enabling wireless devices to transmit a plurality of orthogonal preambles simultaneously to an access node, thereby increasing the probability of at least one preamble being heard by the access node, and minimizing the risk of preamble collision with another wireless device. Different classes of devices may be configured to transmit different numbers of preambles, depending on a priority level for that class, for purposes such as emergency communications, real-time applications, etc. Parameters including relationships between specific priority levels, device classes, application classes, quality of service, and number of preambles permitted, may be broadcast or otherwise communicated to wireless devices by the wireless network.

Abstract: Reducing latency in a wireless network includes initiating a sensing period for measuring signal indicators of a plurality of frequency channels of an unlicensed spectrum, determining that one of the plurality of frequency channels is able to sustain a traffic load, interrupting the sensing period, and scheduling one or more cellular subframes during the remainder of the sensing period using the one of the plurality of frequency channels.

Abstract: Systems and methods are described for implicit information transfer. Neighboring access nodes may coordinate an Almost Blank Subframe (ABS) pattern for ABS transmissions. Implicit transmit symbols may be assigned to ABS′ of the ABS pattern. Traffic may be scheduled for a wireless device on at least one ABS of the ABS pattern. The neighboring access nodes may use the scheduled ABS to decode implicit information associated with the implicit transmit symbols.

Abstract: Systems and methods are described for improving capacity of voice services for data packet transmission through a wireless network. Application requirements including a data rate for a wireless device may be determined. An access node may determine available resources to transmit data as indicated by the application requirements. The wireless device and the access node may communicate data transmissions wirelessly for use by the wireless device application. Data transmission may be in a first mode or in a second mode depending whether there are sufficient available network resources for the determined data rate. The first and second transmission modes may be generated from a common input such as a wireless device user's voice; however, the second mode of data transmission may be converted in order to consume less network resources.

Abstract: Transmitting downlink reference signals includes transmitting a first plurality of subframes comprising a first reference signal associated with a first antenna port, the first reference signal having a first format within the first plurality of subframes, transmitting a second plurality of subframes comprising a second reference signal associated with a second antenna port, the second reference signal having a second format within the second plurality of subframes, and switching a format of each of the first and second reference signals, such that a third plurality of subframes is transmitted with the first reference signal in the second format, and a fourth plurality of subframes is transmitted with the second reference signal in the first format.

Abstract: Retransmission parameters are determined for a wireless device based on a desired retransmission success rate, that is, a probability that subsequent random access requests transmitted from the wireless device re-initiating a contention-based random access procedure with an access node will reach the access node. The retransmission parameters are determined based on at least a quality of service associated with the wireless device, a distance of the wireless device from the access node, and a cell load of the access node. The retransmission parameters include a retransmission power and a retransmission backoff window size. A product of the power and backoff window is scaled such that it can be equated with a retransmission success rate.

Abstract: In systems and methods of wireless device communication using carrier priority, it is determined for a wireless device using a lower priority carrier that a signal strength of a higher priority carrier meets a signal strength criteria. It is further determined that a loading of the higher priority carrier meets a loading criteria. When the loading meets the loading criteria and the signal strength meets the signal strength criteria, a handover is performed of the wireless device from the lower priority carrier to the higher priority carrier.

Abstract: A system and method of scheduling communication in a wireless communication network are provided. A scheduling scheme comprising a first subframe and a second subframe can be determined to communicate data between a first access node and first wireless devices, and a second access node and second wireless devices. A resource request can be received from one of the first wireless devices. An interference indication can be determined based on the resource request. The first access node can be instructed to communicate with the first wireless devices during the first subframe and the one of the first wireless devices can be instructed to transmit data to the first access node during the second subframe when the interference indication meets an interference criteria. The second access node can be instructed to transmit data addressed to at least one of the second wireless devices during the second subframe.
